Slick
Slick (Scala Language Integrated Connection Kit) is a modern database query and access library for Scala (by slick)
Project mention: Show HN: Node.js ORM to query SQL database through an array-like API | news.ycombinator.com | 2024-09-05Scala has a library called Slick which takes a similar approach: https://scala-slick.org
The DSL is nice for simple querying and for composing queries based upon user input. But, for anything slightly complex, I found it's better to just use regular SQL.

ScalikeJDBC
A tidy SQL-based DB access library for Scala developers. This library naturally wraps JDBC APIs and provides you easy-to-use APIs.
> Slick
Totally agreed, Slick is definitely not a good way to access the database. It massively over complicates things and was a massive oil spill that destroyed the maintainability of many codebases. But that's not really Play, specifically, just a library that lots of people used with Play. I personally was always more a fan of https://scalikejdbc.org/, if not just plain JDBC
> It was in state of semi-abandonment for several years
Yes, this is my main complaint. I remember on the front page for like 5 years after TypeSafe Activator had been totally removed from the internet, the Play website was still showing Activator commands. To this day, the Play site still hasn't removed their line about how they support CoffeeScript and Less.
> Guice (in 2.4 afaik) was a terrible mistake, completely unnecessary and at odds with the Scala philosophy
